Netizens had a debate on the age range for idols to debut.

Although there wouldn't be a set formula, netizens debated whether it would be more ideal or less to debut at an younger age. Two age ranges came up: 15-17 years old and 18-19 years old.

With the former, netizens argued that it would best for idols to debut as early as possible. The three points they made were: 

"You can watch them grow up as they grow older. A younger age means they have lots of other opportunities in the future, so age itself can be their weapon. It also takes a longer time these days for idols to gain popularity, so starting early is good; especially for male idols who need to service in the military."

Meanwhile, others argued that idols should be at least 18 or 19, in order to be mature enough for debut. 

"Seeing idols who are too young isn't so comfortable for viewers. Debuting at such a young age isn't good for their own psychology; it is also linked to the physical growth of the idols. It's best for idols to complete their studies and experience school life as an ordinary person."
